When my garage door springs had broken and I could no longer raise the door without a herculean effort, I called Precision not only because of their 4.9-star rating, but the volume of ratings that mean a large number of people have used their service. Now having done business with them, I can vouch for their high rating with one of my own.When the technician showed up (Clint), he was very patient in listening to my questions and clearly explaining the answers, then did a great job not only replacing the broken springs, but overhauling the garage door at my request (that's replacing all the moving parts that wear out over time). My garage door opens and closes the smoothest and quietest it ever has since I've owned the house. I will definitely recommend them to anyone that needs garage door service.read more 

Garage doors cause injury and property damage (including expensive damage to the door itself) in several different ways. The most common causes of injury from garage door systems include falling doors, pinch points, improperly adjusted opener force settings and safety eyes, attempts at do-it-yourself repair without the proper knowledge or tools, and uncontrolled release of spring tension (on extension spring systems).
Test the door balance. A garage door should require only a few pounds of pressure to move it up and down. If springs wear out and lose their resiliency, a power garage door opener may need to work extra hard to lift the door. This can quickly wear out the motor on the opener. Replacing worn-out springs is usually a job for a professional technician.
1. The up-limit switch may need to be moved toward the motor unit. This switch is usually a simply touch-lever mounted on the end of the track near the motor unit, and if it is too far ​away, the motor will stop the door before it fully opens. The solution is to move the switch closer to the motor unit. This is a somewhat rare problem, and will usually show itself immediately after a new garage door opener is installed.
Because garage door springs and openers can degrade over time, it’s important to occasionally test this safety feature. With the garage door open, place a solid object such as a 2-by-4 board or a cinder block where the door will close. Never test any safety feature using your or another person’s body. With the board or block in place, press the close button. If working properly, the garage door should close on the obstruction and immediately reverse the closing operation when it comes in contact with it.
Since most yards entertain play activity including baseballs and other sporting equipment, it's no surprise that garage doors experience broken glass from time to time. Regardless of the cause, it's important to repair glass quickly, since broken glass in a garage is a safety issue, a security problem, and an invitation to every bird and insect in the neighborhood to take up residence in your garage. Fortunately, it's not difficult to replace a pane of glass. The techniques are exactly the same as for replacing glazing in a house window.

It is precisely on those coldest days of the year when you most need and appreciate the convenience of opening and closing your garage door quickly. Sadly, that's exactly the kind of day when moisture and cold can conspire to make this difficult. Garage doors can and do freeze to the garage floor. Sometimes it is just a minor icy connection between the two that can be broken when you hit the opener button. If the door refuses to budge on the first attempt, though, resist the urge to keep banging on the automatic opener button. This is likely to cause a more serious problem with the garage door opener—including, but not limited to, stripped gears, broken springs, and a burned-out motor on the opener.
Response time was excellent. Alex was punctual, friendly, and knowledgeable. I had a 23 year old opener that I needed to replace. He came out and replaced it. It didn't take too long and he was professional in every way. I hope this new unit gives the service and longevity of the old one. We will see. From my experience with Precision Overhead Garage Door Service and Alex, I would use them again and I recommend them.read more

Using your drill, add tension to the torsion spring. This system uses a single spring for a double door, but many manufacturers use two springs for a double door. The painted line on the spring acts as a gauge for the number of turns you put on the spring. To keep the bar from turning while you’re adding tension, attach a locking pliers to the bar on both ends of the spring. Apply lubricant for garage doors to the spring.
